I found what I thought was a possible death for Henry Magee 19th June 1924 in Gulladuff, aged 70 which would have meant he was born c.1853/54, but obviously if he married in 1860 he would have been born in the 1830/40's and therefore a lot older than 70 if he died in 1924.
Also found one for David Downey 24th May 1921 in Magherafelt, aged 70.
Both locations and ages seemed to make sense but now am not so sure.
